JOSEPH KINDL, OF GLEN U'LLIN, NORTH DAKOTA.

GULTIVATOR.

Specification of Letters Patent.

Application filed December 16, 1911. Serial No. 666,160.

To all whom it may concern:

Be it known that I, JOSEPH K'INDL, a citizen of the United States, residing at Glen Ullin, in the county of Morton and State of North Dakota, have invented certain new 41nd useful Improvements in Cultivators, of Ai'hich the following is a specification, refsnce being had to the accompanying drawlngs.

QThisi IiYention relates to agricultural apparatus'and more particularly to improvements inplows and the like and has for its object to proi ide means for suitably breaking up the soil dug up by a plow or cultivator.

'Another object of this invention is to have the parts of this device adjustable to suit all thefconditions arising.

-A further object of this invention is-to have the various parts readily accessible for inspection and repair and of a construction to permit it to be quickly installed on an ordlnary plow without interfering with the present arrangement of its parts.

Other obyects of this invention will become apparent as it is more fully set forth. In the accompanying drawings which illustrate, by way of example an embodiment of this invention Figure 1 represents a view in perspective of a plow provided with a device embodying this invention. Fig. 2 is a detail of the frame used in connection with knives for the purpose of breaking up the soil dug up by the same. Fig. 3 is a detail of ,a mechanism used for adjusting the plow in various positions so that its plow point will dig suitably into the ground; and Fig. 4 is a detail perspective view of aplurality of knife holders and securing plates. Fig. 5 is a detail view showing the construction of the knives.

Similar reference characters refer to similar parts throughout the drawings.

In the appended drawings, 1 represents a plow beam of usual construction which has its front portion 2 slotted to permit an adjustable rack 3 to move freely therein. Fas-' positions, so that the front portion of the plow will be tipped at the most desirable angle for the work in question. Means are provided for raising the rack 3 comprising a lever 17 ard 18.

A flat metallic V shaped frame 8 having upwardly bent end portions 9 provided'with longitudinally disposed slots 10 is secured to one sideof the plow beam. To brace the frame and hold it steady I provide an angu lar member 11 having a longitudinally disposed slot 12 in one of its arms. The other arm of this member is secured to the apex of the frame 8 while the first mentioned arm is fastened to the plow beam on the opposite Side from that carrying the frame. The slots 9 and 11 are adapted. to receive securing members and permit vertical adjustment of the frame.

Disposed on the frame 8 are a suitable number of knife holders 13, which are secured thereto by means of bolts 14, as is clearly shown in the drawings, and which have their shank portions downwardly extended and provided'with holes 15 therein so as to permit the knife points 16 to be held securely thereto. The knife points 16 are disposed at an angle to their'shank 16' for a reason to be hereinafter stated.

Securing plates 20 are formed integrally with the top ,of the holders 13 and bent at right angles to the shank portions so as to lie in a plane parallel to butabove the top edges 21 of the holders. The. securing plates are of greater width than the thickness of the holders and have aside edge in pivotally mounted on the standthe same vertical plane as one face-0f the holders. Bolt holes 22 pass transversely through the securing plates 20 and receive the bolts 14. which fasten the holders to the frame 8. The structure of the holders is such as to permit them to be arranged in overlapped relationship on the frame 8. Each securing plate rests upon the top edge 21 of the following holder 13, which arrangement is very advantageous in that it serves to brace the holders and also to secure them more firmly to the frame. This arrangement is clearly shown in Fig. 4. Since the faces of the holders 13 lie in a plane parallel to the front arm of the frame 105 8, it is necessary, in order that the knives cut properly to have them disposed .at an angle to their shanks 16, as. shown in Fig. 5. This arrangement causes the cutting edges of the knives to lie in the line of draft, so that they will effectually accomplish the work intended.

The adjustability of the frame 8 enables the various knives to be disposed on the plow points suitable to the work in question. This adjustment is made by loosening the bolts of various parts of the frame to the beam, and adjusting the latter, after which the bolts are tightened again so that the frame will be held securely in position.

Having thus described this invention,

what is claimed is:-

1'. In a cultivator attachment, the combination with. a V shaped frame secured to.t he plow beam, of a plurality of knife holders having downwardly extending shank portions to which the knives are attached, and

2. In a cultivator, the combination with a V shaped frame secured to the plow beam, of a plurality of downwardly extending knife holdershaving their faces alined with the front arm of the V shaped frame, the holders being provided with securing plates formed integrally with the top edges thereof and disposed in a plane parallel to but above the same, the securing plates being of greater width than the thickness of the holders and having a side edge n the same vertical plane as one face of th holders, said securing plates being arranged in overlapped relationship on the front arm of the frame, and knives secured to said holders and twisted to bring their cutting edges in the line of draft. t

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

JOSEPH KINDL.
